| Summary: | The designs of small-scale unmanned aerial, land and water vehicles are currently
being researched in both civilian and military applications. However, these unmanned
vehicles are limited to only one and two mode of operation. The problems
arise when a mission is required for two and three-mode of operation, it take two
or three units of vehicles to support the mission. This thesis presents the design
and analysis of an Unmanned Small-scale Air-Land-Water Vehicle (USALWaV).
The vehicle named as a “three-mode vehicle”, is aimed to be an innovative vehicle
that could fly, move on the land and traversing the water surface for search and
rescue, and surveillance missions. The design process starts with an analysis of requirements
to translate the customer needs using a Quality Function Deployment
(QFD) matrix. A design concept was generated by developing an optimal configuration
for the platform using QFD with a non-exhaustive comparison method.
A detailed analysis of the concept followed by designing, analyzing and developing
main components of the drive train, main frame, main rotor, rotor blades,
control system, transmission system, pontoon mechanism and propeller system.
Further, the analysis was done to determine the vehicle weight, aerodynamics,
and stability using several software; SolidWorks, XFLR5, and Matlab. Then, the
model of USALWaV has been fabricated, tested and successfully operates using
remote control system. The final USALWaV configuration is main coaxial rotor
460 mm in diameter, propeller diameter 85 mm, weighing 550 grams; it is capable
of hovering and flying with forward speed between 0 and 0.7 m/s, move forward
and backward speed between 0 and 0.11 m/s, and operation speed between 0 and
0.47 m/s on the water surface. It is powered by an Xtreme Lithium Polymer battery,
and has an endurance of 10 minutes. The main contribution of this design
results is provide a new concept of an unmanned vehicle system in three-mode of
operation i.e. in air, land and water surface. |
